lt f-will tenet-ed that the retaining action, whether it be through" thespring" clip modifica tion of' Fig.4'or that of Fig 5, isactuallypredicate'd upon the coordinated eife'ct of the two spring clipsat therespectiveendsofthefguide, as indicated above. Thus as shown inFig. 2, for example, a clamping means is aifixe'd to each of theends It"and It" of the guide, andtheretainingfunction and gripping action is inefie'ctaffo'rde'd by the combined function of both; clamping members,relative" to sides I and 'l of the powertable. V v I The" positioning ofthe guidewith respect to the presser foot is largely determinableby thecharacteristics of the work contemplated, and the" diagrammaticindications of Figs. 6, 7', and 8 are illustrative of the practicableflexibility and simplicity of attachment and adjustment'attaim able'pursuant to thepres'ent invention.

Concerning the positioning and adjustment'details of the invention, itshould be noted that either edge 8 or edge 9 of guide ii may afford therequisite aligning surface relative to the p-resser foot, except wherean extremely narrow spacing in the form of a seam or tuck or the likeis'desired. Moreover the guide is adapted and intended for transversepositioning across the entire width of the power table. Thus itslongitudinal dimension will desirably exceed that of the power tablewidth to an extent sufiicient to permit the guide either to lie upon orproximate to the" power table, with ends [5, I 6', positionedsufficiently close to sides I and? of the table for attaining therequisite gripping and retaining function by the clamping attachmentsaffix'ed to said ends.

in accordance with Fig. 6, which is essentially an enlarged detail ofthe relative position of guide and presser foot shown in Fig. 1, theguide memher 5 extends transversely of the power table, as previouslystated, and is located at the right of the presser foot 4, with the side8 of the guide being in substantial proximity to the edge 34 of thepresser foot. Pursuant to this modification, the adjustment of the guiderelative to the presser foot is restricted substantially to the spacebetween the said presser foot 4' and the base 2 of the machinesuperstructure. As an illustrative indication, and not limitative, thisdistance may approximate 7 inches more or less for the average powermachine, and it will be understood that this may be subject to variationdependent upon the characteristics of a given machine.

With further reference to Figs. 1 and 6,- the dimension of the seam, hemor tuck available by the positioning of the guide as shown comprisesapproximately the distance between hypothetical line 35 and side 3 ofthe guide. In this connec-- tion the said line 35 in effect correspondswith the needle path or stitching line, and is positioned substantiallymidway of the presser foot opening 36. Thus the pertinent hem; seam ortuck may be'subject to enlargement by locating the guide at anypredetermined position transversely of the power table, between the edge34 of the presser foot and the said base 2 of the machinesuperstructure.

The sketch indicated by Fig. '7 likewise positions the guide 5 to theright of edge 3 1 of the presser foot. However the side 9 of the guideis directed toward the said presser foot, and'infact the edge '34thereof is located essentially within the rabbet 5. With this adjustmentof guide 5, it will be seen that an extremely narrow hein, sand or tuckof requisite uniformity-is attainmedian line of needle eases of eaforesaid h pothetical r this expedient t edge or face 9 of the therumor the ukeiirniis modification wiii approximate the distance betweenthe'-said*line 35 and the edge or side'- 9" of the guide member. It willnevertheless be" understood that-even though the rabbet is directedtoward-edge 34- of the pres'ser "foot, the" guide may be subject topositioning anywherein'the zone 3 3 between the median'line35 of'the'presser foot'and thebase 2' or the machinesuperstructure:

Fig. '8 reveals the guide positii'med to the left of the Dresser foot,thereby affording comparatively unlimited variation in positioningth'eguide transversely of the power table; theliinita'tions beingdeterminedby the length of that portion of thepower table which extendsto the left of the presser foot 6: As shown in Fig. 8side- 8 of guide 5is located in proximity to" edge a? of thepresser foot, and th dimensionof the hemseam or tuck, pursuant to this adjustment, comprises thedistance between the said median stitching line or' needle path 35"andthe said edge 3 of the guide; As the guide 51's adjusted in zone 33toward'th'e left, the distance between line Stand edge 8 willbeprogressivelyincreased, and the pertinent dimension may be.extend'e'dto the point where the guide 5 is positionedalbn the edge 36of the power table. While the showing of Fig. 8 positions" edge 8 of theguide member toward edge 31 of presser foot 3, it will be understoodthatedge '9 of the guide member likewise may bepositioned contiguous edge 3?of the presser foot, and under such circumstances, the rabbet 6 may becorrelated with the said presser foot edge 31. By advantages attainablefrom the rabbet, especially that of affording. an extremely narrow,uniform hem, tuck or the like, is provided when the guide 5 is locatedon the left of the presser foot with the said rabbet'fi, on guide,adjacent edge .31 of the presser foot.

Accordingly the positioning of the guide to the left ofthe presser footperm-its the forming of very narrow, accurate hems, tucks, seams, or anydesired stitched spacing of improved uniformity similar to that-affordedby the attachment of the guide to the right of the presser foot, therequisite being that the rabbet 6 shall be contiguous the pertinentpresserfoot edge Thus while positioning the uide on the-right-ofthepresser foot afiords the possibilitiesfor progressive variations in thewidthof the stitched spacing that are essentialiy limited to thedistance between line 35 and the base 2 of the machine superstructure,exclusive-oi the surface width 49 of the guide, the progressivewidthvariations at- .tainable through locating the guide on the left of thepresser foot are substantially determinable by the distance between line35 and edge 380i the power table, iikewise' exclusive cfthe' surfacewidth 40 of the guide 5.

Accordingly in View or its flxibili tyiri adaptatio'n both to the rightof the presser foot and to the left thereof, the guide 5 comprises asimplified, adjustable device permitting accurate, uniformed stitchedspacings, which are subject to predetermined and widely diversifieddimensions relative to the needle path or stitching line 35. This isevidenced by its sphere of function extendin longitudinally of themachine power table substantially from edge 38 thereoffto the saidsuperstructure base 2, or difierently stated, from said tableedeete tomedian line 35 'on the left or the presserroct-ana rromsaio finest-tothe superstructure base 2 on the right of the presser foot.

The above description has illustratively referred to guide 5 in theconsideration of the various adjustments attainable, as exemplified inreference to Figs. 6, 7, and 8. However it will be clear that guide Itis subject to similar adjustable positioning and affords comparable attributes of flexibility in its adaptations, as well as accuracy anduniformity as a power table guide, since the said guide Ill is to allintents and purposes fundamentally similar to guide 5. As indicatedhereinabove, the difference between guide 5 and guide it is predicatedon the positionin of the rabbet 6, this being essentially determinableby the characteristics of the sewing machine, particularly with respectto the pertinent location of the machine superstructure together withthe presser foot location relative to the transverse dimension of thepower table. Differently stated the position of the presser foot withreference to the side or edge 1 or 1' of the power table i determinativeof the position of the rabbet along the longitudinal dimension of theguide.

As for the dimension of the guide, its length will be determined, aspreviously indicated, by the transverse dimension of the power table,with the angularly disposed portions l6, l6 thereof being of sufficielltlength to permit the engagement of the attached clamping means with thesides 1, 1 of the power table. Since the width or transverse dimensionof sewing machine tables is essentially standardized, the regulatedproduction of appropriate length guides, pursuant to the invention willbe apparent to those versed in the art.

Merely by way of example, the longitudinal dimension of a desirablefabricated guide embodiment applicable for a known sewin machine powertable, measured between the inner surface of angularly disposed portionsl5, I6, is approximately 16.5 inches. As for the surface width thereof,this dimension may be substantially subject to the dictates ofpreference, and for the said fabricated guide embodiment, this dimensionis approximately /8 inches. As in the case of the other guidedimensions, the height or thickness of the guide may be determinablelargely on the basis of preference, and the relevant dimension of thesaid guide embodiment is approximately inches.

In connection with the angularly disposed pertions I 5, it, theeffective length thereof may likewise b subject to variation dependent,for example, upon the dimensional characteristics of the power table,and in the aforesaid guide embodiment the length is approximately 1 /8inches measured from the under face of the guide-that is, along theinside surface of said portions iii or it and thus excluding thethickness or depth of th longitudinal portion of the guide, which asindicated, is positionable transversely of the tables and may beapproximately /4 inch in height or thickness. By way of reiteration, thedesignated dimensions are merely illustrative of a desirable embodimentand are in no sense critical or in any manner intended to be restrictiveof the invention.

The guide member may be fabricated from diversified materials, such asmetals, synthetic resins including artificial rubber-type materials, aswell as from natural rubber, et cetera. While the clamping means shownin Figs. 4. and 5, preferably of metal derivation, are applicable to anyof the indicated types of guide materials, the modification of Fig. 4 ismore expediently adapted for metal guide members than for resin orsimilar guides, in view of the greater amenability to threadingmanifested by metal articles. As for the clamping attachment of Fig. 5,this is entirely effective with synthetic resins, rubber-type materialsand the like, as well as with metals.

While it is not intended to be restricted to any particular type ofmaterial for fabrication of the guide, quite desirable metals have beenfound to be aluminum as well as various alloys thereof, and steel, etcetera. Similarly effective are resin guides, such as those derived fromLucite, phenolaldehyde resins, polystyrene resins, etc.

The procedure involved in the utilization of the invention will conformwith the fundamentals pertaining to the supply of fabric to the powertable of a sewing machine for the purpose of applying predeterminedstitched spacing thereto. Thus the fabric is normally fed transverselyof the power table-that is, across the same, and a folded end of thefabric, determinative of the width of the stitched spacing may bepositioned adjacent the edge 8, or 9, in accordance with thepredetermined adjustment of the guide 5, while the line of stitching isdetermined by the position of the presser foot. As the folded edge ofthe fabric is passed across the power table in contact with thepertinent edge of the guide, the stitching, conforming with line 35 isprovided by the usual function of the needle in coordination the presserfoot.

Whether the guide 5 will be placed to the right of the presser foot orthe left thereof, and the relevant positioning of the rabbet S withrespect to the presser foot will be subject to the nature of the spacedstitching requirements and determinable by the operator versed in thesewing art.

- Where the distance between line 35 and base 2 of the machinesuperstructure is approximate? 7 inches, and the spaced stitchingdesired is less than 7 inches, the guide 5 may effectively be located onthe right of the presser foot. This location of the guide is desirable,where it is expedient as above indicated in view of the predeterminedwidth of the spaced stitching, since it permits the length of zone 33 ofthe power table, extending from the line 35 to edge 38, for the handlingof substantial lengths or masses of fabric. Similarly this location ofguide 5 is effective for extremely narrow stitched spacings attainedthrough the positioning of rabbet t to the right of and contiguouspresser foot 4.

Where the spaced stitching desired exceeds that attainable with thpositioning of guide 5 to the right of the presser foot, it is essentialthat the guide be placed to the left thereof. As previously indicated,this location of guide 5 permits the production of spaced stitching fromthat of an extremely narrow width when rabbet 5 is contiguous edge 31 ofthe presser foot, to an unusually enlarged width attainable by theadjustment in the location of guide ii toward the edge 38 of the powertable, as aforesaid. As previously indicated the maximum widt ofstitched spacing with the positioning of guide 5 to the left of presserfoot 4 corresponds with the distance between line 35 and the edge orside of the guide which faces the presser foot, the opposing side oredge of the guide being aligned with edge 38 of the work or power table.

Pursuant to the invention, there is provided a comparatively simple,sturdy guide member, especially applicable in a combinative association:9 witha sewing machine, attachable to the ma- :chine power table, and.afiording .aldiversified rflexibility in (its adjustmentand functionnot heretofore attainable. Thus the adjustable and variable positioningof the guide member permits an unusually wide latitude in theforming.ofstitched spacings of enhanced accuracy and uniformity, from those ofextremely narrow width progressively to those of extremely enlargedwidth. By virtue of its characteristics, the invention is adapted foruse by any sewing machine operator and without any unusual requis'itesof mechanical skill. Moreover indicative of the features and utility ofthe invention are the many adaptations and flexibility thereof pertinentto'the formulation of spaced stitching of improved accuracy anduniformity and subject to extremely wide variations in the relevantdimensions such as the spacing'width. As previously described, theramifications of the :said stitched spacings illustratively include the,production of hems, tucks, seams, edging, as well as the attachment ofdiversified types of itrimmings .to a garment.

In accordance with the disclosure herein, the details of descriptionpertaining to the various figures of the drawing are directed topreferred modifications of the invention. It will, however, "beunderstood that these desirable embodiments are intended to beessentially illustrative, rather than restrictive or limitative, and aresubject to substantial variation within the purport and scope of theinvention herein.
